After looking at the previous question on liquid airlocksprevious question on liquid airlocks, I noted that the main problem with technology is that the force of gravity is far too weak on any body that an airlock would be a useful piece of equipment for the liquid airlock to work effectively.
So, lets replace gravity with the magnetic force, and the liquid with a ferroliquid, and see what happens.
The obvious advantages of such an airlock would be that it could be used in a continuous manner, perhaps for mining operations (for moving large machinery and for moving a conveyor belt of minerals).
Would this work in a vacuum?
